Aluminium fingerboard glue

Hi.

Sika 221 would be an ideal choice if it was something else than an instrument. Might be too elastic and dampen the vibration too much.

Any medium hardness epoxy would most likely to do the job. Can't recommend any though and the selection here might differ a bit from Yours anyway .

Got a picture of the glue ? Most likely a devcon bonding product as alot of things adhesive agents do not stick to aluminum very well.

 

Polyurethane glue should stick.

 

a good prep with muratic acid and a good presand with something rough 60-80grit and a good urethane adhesive should work but which one ? There are numerous urethane adhesives. I would think a 2 part catalized would most likely be better and then of the 2 parts which one will work the best ?

I am sure Devcon make a bonding agnet for this exact application.

I might be inclined to use this.

It is flexiable enough to allow for the wood and aluminum to have fiarly different exspansion contraction carecteristics and stay glued together. They have other similar glue in this family. I have never tried bonding wood and aluminum so my knowledge runs out here in a instrument setting.
